Jarisch-Herxheimer reaction in complement-depleted rabbits. Histological and immunofluorescence studies of early cutaneous lesions.

The possible role of complement in the pathogenesis of the Jarisch-Herxheimer reaction was assessed in cutaneous syphilitic lesions in two groups of rabbits treated with penicillin; in one group complement was depleted before penicillin therapy. Serial biopsy specimens were similar histologically in both groups. The activation of the complement pathways did not seem to play a role in the pathogenesis of early cutaneous syphilitic lesions in rabbits during the Jarisch-Herxheimer reaction.

[Skin syphilids, only incidental findings].

Six cases of syphilides- rarely seen cutaneous manifestations today--are reported and the difficulties in finding the correct diagnosis are stressed. Considerations with particular reference to the differential diagnosis of clinically and histomorphologically similar diseases are discussed. Beside case history and serological tests it is of overall importance to bear in mind the possibility of late syphilis.

Facial and oral aspects of some venereal and tropical diseases.

Diseases of the tropical areas include some venereal diseases, and they are still very prevalent in some countries; Brazil is one of them. Very few cases are originated in large cities, as Rio de Janeiro, but at the University Hospital of the Federal University of Rio de Janeiro we also see those patients who come from the interior of the State of Rio de Janeiro or from other states to seek medical care at better equipped hospitals for this type of investigation and therapy. Venereal and tropical dermatoses have many different cutaneous manifestations and may affect skin in several locations. The face is one of the affected areas especially when the disease has a predilection for cartilage, oral and/or nasal mucosa. Alterations observed on the skin of the face and on the mucosa of the mouth of some tropical diseases, such as leprosy, leishmaniasis, paracoccidioidomycosis, donovanosis, and syphilis, as they are observed in Brazil, are presented and discussed in this article.

Perianal eosinophilic granuloma resembling condyloma latum.

A 2 1/2-year-old boy with eosinophilic granuloma confined to the frontoparietal bones developed a rectal fissure that progressed to a perianal plaque resembling condyloma latum. Biopsy confirmed the presence of many Langerhans cells, and therefore a diagnosis of eosinophilic granuloma involving the skin was made. Although rare, eosinophilic granuloma can be associated with cutaneous lesions, sometimes isolated and mundane in appearance. It should be considered in the differential diagnosis of perianal lesions.

Metabolic-associated skin disorders.

There are a host of metabolic disorders with cutaneous manifestation. Often the clinician can use dermatologic clues that can provide insight into the systemic disease. Cutaneous features may be the first sign of an internal disorder. The authors present a capsule of pertinent clinical information about the more common disorders.

Detection by direct immunofluorescence of antibodies to Treponema pallidum in the cutaneous infiltrates of rabbit syphilomas.

By direct immunofluorescence, with use of fluorescein-labeled sonified Treponema pallidum, specific antibodies were detected in the tissue infiltrates of cutaneous syphilomas in rabbits. Specimens from cutaneous and mucosal inflammatory lesions induced by intradermal injection of a keratinous substance from an epidermal cyst served as controls. Granular fluorescence was detected in the dermis of 11 of the 12 syphiloma specimens and corresponded to areas of heavy plasma cell infiltrates, and some fluorescence was found directly on plasma cells identified by subsequent staining with hematoxylin and eosin. This fluorescence could be blocked by preabsorption. Control slides did not show any fluorescence. Immunopathologic techniques using labeled antigens may be of diagnostic value in syphilis and other infectious disorders which feature specific infiltrates.

[Current status of the therapy of granulomatous skin infections].

We report on granulomatous infections of the skin, as well as the current state of therapeutics. Cutaneous tuberculosis and presently desired therapeutic regiments are treated in detail. Diseases regarded as eradicated in Germany, such as brucellosis and listeriosis, do still occur. Their recognition and cure are discussed from a modern point of view.

Demonstration of Treponema pallidum in axons of cutaneous nerves in experimental chancres of rabbits.

After cutaneous inoculation of viable Treponema pallidum subsp pallidum into the skin of chancre-immune or previously uninfected rabbits, organisms move from perivascular connective tissue to localize extracellularly in hair follicles, erector pili muscles, and cutaneous nerves. Large numbers of intact organisms can be seen within the perineurium using electron microscopy, and after extensive sampling a few organisms can be detected within the axon cytoplasm. These findings support the concept that T. pallidum may be able to pass along the nerve fibers to the central nervous system.

Reactivity of various leishmanial antigens in a direct agglutination test and their value in differentiating post-kala azar dermal leishmaniasis from leprosy and other skin conditions.

A direct agglutination test (DAT) for the detection of post-kala azar dermal leishmaniasis (PKDL) was evaluated in conditions that simulate the disease clinically or immunologically. A reference strain of Leishmania donovani (LEM 1399), and antigen preparations from Leishmania isolates from Bangladeshi patients with post-kala azar dermal leishmaniasis or visceral leishmaniasis were used. A titre of at least 51,200 was obtained in tests of patients with PKDL with all three antigens, whereas a maximum titre of 1600 was recorded in patients with cutaneous leishmaniasis, mucocutaneous leishmaniasis or leprosy. Antigens from dermal isolates of L. tropica (LV 140) and L. braziliensis (LV 65) yielded titres of 1600-6400 in patients with PKDL. The lowest titre recorded in 70 patients tested with the homologous PKDL antigen was 409,600. In patients with leprosy, cutaneous leishmaniasis, syphilis, onchocerciasis, tuberculosis, blastomycosis or vitiligo, titres ranged from 100 to 1600. Tha DAT is better than current parasitological and histopathological methods for the diagnosis of PKDL in areas in which leprosy is co-endemic.

Acquired resistance and expression of a protective humoral immune response in guinea pigs infected with Treponema pallidum Nichols.

Resistance to cutaneous syphilitic reinfection in strain 2 and strain 13 guinea pigs developed gradually 3 to 7 months after primary infection and reached maximum levels at 6 to 7 months after the induction of primary cutaneous disease. Associated with this acquired resistance was the occurrence of Arthus reactions and anamnestic-type antibody responses. Passive transfer of immune serum containing high-titered treponemal antibody into normal strain 2 guinea pigs significantly delayed the appearance and markedly diminished the severity and duration of skin lesions that developed after these recipients were challenged with treponemes but did not prevent the dissemination of organisms to the draining lymph nodes. These findings provide direct evidence that syphilitic infection elicits the formation of serum factors that are, at least, partially protective against symptomatic disease.
